Hundreds of people are assisting police in the search for a Pennsylvania woman who has been missing since September 17, CBS News reported.

The search for Leah Marie Owens, on Sunday morning, drew more than 300 participants and 400 personnel to Bullskin Township. Justin Jellots, Owens’ brother-in-law working with the group Bring Our Missing Home, told CBS that the group used drones, boats, teams on horseback, and ATVs during the search.

"We covered a lot of areas of interest today," Jellots said. "We don't plan on stopping, even though we didn't have anything really solid to go on. As far as findings go, we found a lot of pieces of interest.”

They are planning another search in about a week, he said.

“We at Bring Our Missing Home would like to take this opportunity to thank you for coming out today on Leah’s behalf,” said Cathey Rhodes, the founder of the group, said in a statement on Facebook. “Although we all hoped for a different outcome myself, my team and the family, are humbled at the outpouring of support, concern and love for Leah. Again, thank you for your time and effort today. We appreciate every one of you.”

Police found a Ford Escape belonging to Owens, 31, that had also been missing. Police did not disclose where or how they found the car.

Owens is a white, 5'7" woman with long black hair and green eyes. The slender woman was wearing a peach-colored, hooded sweatshirt and blue shorts when she was last seen, according to the Associated Press.
